What happened to prices between 1945 and 2025
Between 1945 and 2025, the Consumer Price Index went from 18 to 321.943.
Cumulatively, prices increased 1688.6%, which works out to an average of
3.67% per year. Put differently, a dollar in 1945 bought what
$0.06 buys in 2025: the 1945 dollar
lost 94.4% of its purchasing power over
these 80 years.
Consumer prices rose 2.3% in 1945, up from 1944’s 1.7% but
still modest, a rate that understated how much pressure had built up behind
wartime price and wage controls, which stayed largely in place even as the
conflict that justified them came to a close. The year opened with a shock
at home: Franklin Roosevelt died of a cerebral hemorrhage on April 12, less
than three months into an unprecedented fourth term, and Vice President
Harry Truman was sworn in that same afternoon. The war Roosevelt had led for
nearly four years ended without him. Germany surrendered on May 8, and
Japan surrendered on August 15, after atomic bombs fell on Hiroshima and
Nagasaki that month, with the formal signing aboard the USS Missouri on
September 2. Domestic policy kept moving even as the guns fell silent: the
federal minimum wage rose to 40 cents an hour that October 24, the final
step of the schedule Congress had built into the 1938 Fair Labor Standards
Act, up from 30 cents in 1939 and 25 cents at the law’s start. Consumer
prices stood 81.8% above their 1913 level, a gain that would
look modest next to what followed once wartime controls actually came off.
First-class postage held at 3 cents.
Every 1945 amount converts to 2025 at the same ratio, 17.89: $1,000 becomes
$17,886, and $10,000 becomes $178,857.

Year by year: CPI and the value of $100 from 1945
$100 from 1945 had already become $598 by
1985, on its way to $1,789 in 2025; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 14.4% in 1947, and prices fell 1.2% in 1949, the deepest deflation of the period.
Long periods are sampled every 5 years; the calculator above covers any pair of years.
The destination year: 2025
In 2025, prices rose 2.6% and $100 from 1945 had the buying
power of $1,789; the year's average CPI of 321.943 is the level
behind every 2025 figure on this page.
2025 was a year of trade policy and data disruptions rather than an
inflation surge. Consumer prices rose 2.6% on average, a step down from
2024’s 2.9% and well below the 8.0% of 2022. Tariffs announced in April
pushed up prices for some imported goods, including furniture, apparel, and
auto parts, but the effect on the overall index was smaller than many
forecasters feared at the start of the year, in part because retailers
absorbed some of the cost and demand for services stayed steady.
The Federal Reserve held its policy rate steady through the first half of the
year, then began cutting again in September, lowering it in three quarter-point
steps to 3.50–3.75% by December.
The federal government shutdown that began October 1 lasted 43 days, and the
Bureau of Labor Statistics did not publish a CPI for October 2025 because the
survey data could not be collected. The federal minimum wage stayed at $7.25,
and a first-class stamp rose to 78 cents in July.
